HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 653,867, dated J uly 17, 1900. Application filed April 25, 1900. Serial No. 14,324. (No model.)

To (LZZ whom, it may concern:

Be it known that we, EDWARD O. INDEE- LIED and CHARLES B. RUMsEY, citizens of the United States, residing at Binghamton,

5 in the county of Broome and State of New York, have invented certain new and useful Improvements in Heating Apparatus; and We do hereby declare the following to be a full, clear, and exact description of the inro vention, such as will enable others skilled in the art to which it appertains to make and use the same.

Ourinvention has for its object the generation of heat and its utilization in the arts generally. It is particularly applicable to the conversion of a liquid into a vaporous state in a steam-boiler, in the process of dry distillation, &c., and also to the decomposition of matter, such as coal, in the manufac- 2o ture of coke, gas, the.

The invention in the most generic sense comprises two substantially-parallel pipes, one for gas and the other for air, closed at one of their ends and provided with perfora tions along their sides, in combination with a combustion-chamber surrounding the same, said chain-ber being provided With a suitable exit for the products of combustion, but otherwise closed or sealed.

In its more limited sense the invention involves the idea of internal location of the combustion-chamber relative to the matter to be operated upon and includes also means for heating the air and forcing it under pressure to the combustion-chamber, all of which will be hereinafter more fully described, and particularly stated in the claims.

In the drawings, Figure 1 is avertical longitudinal sectional view of one form of boiler, showing our device applied thereto; Ijig. 2, a vertical transverse section of the same; Fig. 3, a vertical section of another form of boiler, showing our device applied thereto; Fig. 4, a transverse section of the 5 same, taken through the center of the combustionchamber; and Fig.5, a vertical transverse sectional view of it a charged retort, showing the location of combustion-chamber and gas and air pipes situated therein and 5c the return-pipes for the products of combus tion.

Referring to the several views, the letter A indicates a boiler, which may be either of a horizontal or upright type, and B a retort. Each device is provided with a suitable heatinsulator b and is mounted upon a suitable base, which is formed with an air-chamber having an inletfor the admission of air. The several devices and their bases may be of any desired construction, so long as the base of each is formed with an air-chamber.

The letter D indicates a combustion-chamber, preferably circular in cross-section and of considerable length relative to its crosssectional area. This chamber is provided with three openings, two of which serve as ingress-openings for the fuel elements and the other as the egress-opening for the prodnets of combustion and is otherwise closed or sealed. It may be stated that this cham- 7o ber need not of necessity be a part of the burner structure, but may be formed by the apparatus containing the matter to be operated upon, or may, in fact, be a part of said matter as, for example, when it is desired 73 to heat a broken pipe for repairs said pipe may itself be made to form the combustionchamber.

lVithin the combustion-chamber are the gas and air pipes E and F, respectively. These pipes are perforated along their sides, closed atone of their ends, and preferably extend substantially the length of the cornbustion-chamber. The perforations of the gas and air pipes should for the best results be so arranged that the jets of one will cross those of the other pipe.

Gr indicates a fuel-supply tank which communicates with the gas-pipe. The fuel used may be either a fixed gas or liquid fuel adapted to be vaporized and introduced into the combustion-chamber in a vaporous state.

H indicates a fan having communication with the air-pipe and adapted to force air under pressure therethrough into the combustion-chamber.

In order to utilize to the greatest degree the heat generated, we have provided an airheating chamber I, through which the prod nets of combustion are caused to pass before too escaping into the atmosphere, said air while in its heated state being introduced into the combustion-chamber by the means above described. The air-heating chamberis provided with a suitable air-inlet f and an out-let i.

Situated within the heating-chamber is a coil K, having comm unication with the egressopening ofthe combustion-chamber and opening out into the atmosphere through the Wall of said air-heating chamber. It will be understood, however, to those skilled in the art that the air may be caused to pass through the coil and the products of combustion through the chamber containing the coil.

In order to produce perfect combustion, the volume of air introduced to the combustionchamber must far exceed the volume of gas. By the construction and arrangement of the parts herein described the air passing through the perforations of the air-pipe in jets at a high velocity and crossing the gas-jets tends to communicate thereto motion in the same direction, resulting in a more thorough agitation and intermingling of the fuel elements. Moreover, as the pressure of the air-jets is communicated in all directions in the combustion-chamber it follows that those nearest the egress-opening tend to retard the escape of the gases in other parts of the combustionchamber, whereby the fuel elements are held for a longer period within the heat zone, resulting in their more complete combustion.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is

1. The combination of a combustion-chamber having an egress-opening, two perforated fuel-pipes, closed at one end, situated in the combustion-chamber and extending its length, said combustion-chamber being of such cross-sectional area as to provide but a limited space surrounding the fuel-pipes, so that the fuel elements issuing from the pipes and the products of combustion are forced to move longitudinally thereof toward the egress-opening, means for introducing gas to one of said pipes and means for introducing air to the other of said pipes. V

2. The combination of a combustion-chamber provided with an egress-opening and perforated gas and air pipes situated in the chamber and extendingits length, said combustionchamber being of such cross-sectional area as to provide but a limited space surrounding the fuel-pipes so that the fuel elements issuing from said pipes and the products of combustion are forced to move longitudinally thereof toward the egress-opening, the air and gas being introduced to the combustionchamber under pressure.

said pipes and the products of combustion are forced to move longitudinally thereof toward the egress-opening, the perforations in said pipes being so arranged that the jets issuing from one pipe will cross those issuing from the other.

4. The combination of a chamber to contain the matter to be heated, a combustion-chamber arranged therein and completely sur rounded by the said matter, said combustionchamber being provided with an exit-opening, perforated gas and air pipes, closed at one end, situated within the combustion-chamber and extending longitudinally its length, the said combustion-chamber being of such crosssectional area as to provide but a limited space surrounding the gas and air pipes, so that the fuel elements issuing from said pipes and the products of combustion are forced to move longitudinally thereof toward the egress-opening, and means for supplying gas and air respectively to said pipes.
